Under the connection of the connecting screw 2, the flange 1-5 with the claw on the right side and the groove base 3-5 can be regarded as a whole, when power is transmitted to the groove base 3-5 of the overload protection component 3, the groove base 3-5 is electrified to rotate together with the groove 3-6 matched with the groove base 3-5, the groove 3-6 extrudes the steel ball 3-12-1 of the thimble component 3-12, and then the steel ball 3-12-1 pushes the pin shaft 3-12-4 to axially slide until the reaction force in the thimble component 3-12 is equal to the thrust of the steel ball 1, the pin shaft 3-12-4 stops sliding, and further the pin shaft 3-12-4 drives the thimble component 3-12 to synchronously rotate along with the groove base 3-5, and further drives the thimble seat 3-8 and the right shaft sleeve 3-10 to synchronously rotate; in the rotation process, the torque load torque is increased, the acting force of the groove 3-6 for extruding the steel ball 3-12-1 is increased, the steel ball 3-12-1 further pushes the pin shaft 3-12-4 to slide, the internal reaction force of the thimble assembly 3-12 is increased to reach new balance, when the load torque is increased, the internal reaction force of the thimble assembly 3-12 is increased to a set value, the thimble assembly 3-12 is disengaged, the steel ball 3-12-1 and the pin shaft 3-12-4 are separated from contact with the groove 3-6 under the pushing of the groove 3-6, and at the moment, the overload protection assembly idles and participates in the torque to approach zero; under the support of the bearing 3-4, the groove base 3-5 idles without resistance, the rotation of the top needle seat is stopped under the action of load, and then the overload protection function is completed. After the fault is removed, the pin shaft 3-12-4 is pushed to drive the steel ball 3-12-1 to be matched with the groove 3-6 again in a clinging manner to realize resetting, and the structure is convenient to reset.
After the product serialization, when the operating mode changes, when the elastic vibration reduction assembly 1 or the overload protection assembly 3 with different performance requirements needs to be replaced, only the connecting screw 2 needs to be disassembled to match the assemblies with the same interface size, and the different series of assemblies can be replaced.
